In secondary school, I had a chance to visit a supercomputer center with a Cray Y-MP (like this one: http://planetromero.com/2010/01/gametales-cray-ymp http://planetromero.com/2010/01/gametales-cray-ymp). Turns out it's just a big cabinet. Hooked up to other big cabinets. Oh, and when you sat down at a login terminal, it was just a Unix box. Coolest thing about it was the attached bench (Cool! I sat on a supercomputer! Hmm. Not very comfy.) sigh From the outside, the datacenter is an inaccessible realm of high technology, carefully engineered to maximize various important features. From the inside, it's cabinets and wiring and plumbing.
